Respiration rate and its effect on mass loss and chemical qualities of 'Fuyu' persimmon fruit stored in controlled atmosphere

The objective of this research was evaluate the effect of two CO2 partial pressures in ultra-low oxygen on the mass loss in function of respiration, oxygen consumption, respiratory rate and other characteristics of 'Fuyu' persimmon during 12 weeks in controlled atmosphere (CA) storage at temperature of -0,5°C. For thus, one experiment was carried out with the followed CA condition: [1] 0.15 kPa O2 plus 2.0 kPa CO2 and [2] 0.15 kPa O2 plus 6.0 kPa CO2. On this study was verified that the respiration (carbon dioxide production) was responsible for 24% of total mass loss. The total mass loss is significantly affected by the controlled atmosphere storage. The 2.0 kPa CO2 promotes changes in the respiratory quotient during the storage period and keep higher mass loss in function of respiration (CO2 losses) and lower soluble solids after storage.
